Choose KENKI DRYER – The Ultimate Solution for Drying Sticky and Adhesive Materials
When it comes to drying materials with strong sticking or adhesive properties, KENKI DRYER stands apart as a world-leading low-temperature steam dryer with 11 international patents (2 in Japan and 9 across 7 countries). Even if the drying object has a high moisture content and strong adhesiveness—such as dewatered sludge from wastewater treatment plants—KENKI DRYER can dry it smoothly, efficiently, and without clogging, thanks to its unique, patented anti-clogging mechanism.
Unlike conventional dryers that often experience internal clogging and discharge issues, KENKI DRYER’s innovative design ensures consistent and stable drying performance, even with materials that form lumps or adhere to internal surfaces. During the drying process, materials like sludge tend to clump together due to flocculants used in wastewater treatment. KENKI DRYER addresses this by gently crushing and reducing the size of the material, ensuring even heat transfer throughout. As a result, both the surface and the inner parts of the material are completely dried without any unevenness. Low-Temperature Drying for Upcycling and Sustainability
KENKI DRYER operates using low-temperature indirect steam drying, minimizing changes in the composition of materials. This allows dried sludge to be reused or upcycled as compost, soil conditioner, or fuel. Since the system uses steam as the heat source, it enables carbon-free and energy-efficient drying, supporting decarbonization goals. When paired with an electric boiler, the system achieves zero CO₂ emissions during operation.
High Thermal Efficiency and Easy Maintenance
The steam-based heat source offers excellent thermal efficiency, meaning less steam consumption and lower operating costs. The dryer’s slow rotation speed (5 rpm or less) minimizes wear on parts, reducing maintenance costs and extending equipment lifespan. Moreover, the continuous drying system enables fully automatic, 24-hour unmanned operation, enhancing productivity and safety.
Environmental Contribution and Resource Recovery
Drying sludge significantly reduces its weight and volume, cutting industrial waste disposal costs and decreasing CO₂ emissions by reducing truck transportation—an increasingly critical issue amid the logistics challenges of 2024 and beyond.
In Japan, where nearly all mineral resources are imported, recovering valuable minerals and phosphorus from sludge has become a national priority. Upcycling sewage sludge not only contributes to decarbonization and circular economy goals, but also helps secure essential resources such as phosphorus, precious metals, and rare metals for future sustainability.

Organic sludge drying / Brochure
No matter how sticky, adhesive and viscous the material is, KENKI DRYER of International Patent can dry it without clogging inside of dryer and with stable operation that no operational trouble occurs because of its unique mechanism. For example, even materials stuck to the blades of one screw, blades of the other screw in the dryer’s body forcibly peels the materials off as they rotate. Since the blades rotate by peeling the material off each other, any sticky, adhesive and viscous material does not adhere to the blade, and the blades continue rotating, peeling, agitating and heating material without stopping while they carries material further. Also, since surface of blades are always renewed and kept clean, heat near the blades is not blocked and it is conducted directly into the materials.
